There are approximately 20 species of cereus cacti ranging from Central/South America through Mexico and the West Indies to the southernmost parts of Florida. While in Key West last summer, I removed some cuttings of unknown cereus origin (from a parking lot) and blogged about them here. Although I assumed my purloined plant was Selenicereus pteranthus, now that it’s bigger I think I snagged a dragonfruit (aka Hylocereus undatus)
Hylocereus undatus is a vining, hemi-epiphytic, broader and fleshier relative of the Selenicereus varieties. As this sprawling cactus gains height, aerial roots assist the upward climb and ensure the plant’s survival if the soil bound roots should fail. What an adaptation!
Flowers in this genus are extremely fragrant and large–up to 14″ long x 9″ wide–and typically appear after 3 years..but only at night. As a side note, the H. undatus along my vinewall just entered it’s 3rd year: I’ll let you know if anything happens!
I hope my American readers are having a fun 4th of July weekend and that Hurricane Arthur hasn’t wrecked your plans along the East Coast! Yesterday’s weather was still unsettled here (as you can tell from the sky below) but Maggie and I spent it beachside anyway!
Until next time…
